NNStreamer: Efficient and flexible stream pipeline framework for complex neural network applications



NNStreamer, a Linux Foundation AI Foundation open source project, is an efficient and flexible stream pipeline framework for complex neural network applications, which was developed and open-sourced by Samsung.


NNStreamer's official binary releases include supports for Tizen, Ubuntu, Android, macOS, and Yocto/OpenEmbedded; however, as long as the target system supports Gstreamer, it should be compatible with NNStreamer as well. We provide APIs in C, Java, and .NET in case GStreamer APIs are overkill. NNStreamer APIs are the standard Machine Learning APIs of Tizen and various Samsung products as well.

Open Source

Open Source

NNStreamer was open-sourced in 2018 on GitHub, It is actively developed since then and has a few sub projects. NNStreamer has joined LF AI Foundation in April 2020.


In general, you may build NNStreamer in any GStreamer-compatible systems.

Usage Examples

Applications of these screenshots require very short lines of code (click screenshots to look at) and run efficiently in inexpensive embedded devices. They can even be implemented as single-line bash shell scripts with NNStreamer.

Example applications are located at GitHub, nnstreamer-example.git and the Wiki page.
